METAL-SHAPING MACHINE.

To all whom it may concern:

Be it known that I, CLARENCE H. RIEGEL, of Niles, in the county ofTrumbull and State of Ohio, have invented certain new 'body portionsthereof rand a further object is to provide a machine of this characterwhich will form corrugations of the type stated extending longitudinallyof the sheet.

The invention will be hereinafter fully set forth and particularlypointed out in the claims. In the accompanying drawings, Figure 1 is afront elevation. Fig. 2 is a plan view. Fig. 3 is an enlarged transversesectional view. Fig. 4. is a dlagrammatic view showing the positions ofthe dies or mandrels before being moved to shape the metal. Fig. 5 showsthe same parts wit the mandrels foreed together. Fig. 6 is fragmentaryview of the completed article. Fig. 7

shows a fragmentary. portion of one set of mandrels. Fig. 8 1s a view ofone of the connecting links.

Referring to the drawings, 1 designates a table which is mountedfon themain frame 2 to which it is adjustably held by clamps and bolts 3 whichpermit the table to be adjusted transversely of the frame, such latteradjustment being controlled by set screws 4. The table 1 is shown ashaving a portion of its surface cut out, as at 5, to form a chamber orco" to be closed by a top or cover 6 which is pivoted to the table at 7.This top is preferably connected by means of a rope 8 to a counterweight(not shown). When the topis lowered it extends over the chamberedportion of the table and is held to the forward thickened portionthereof by locking lugs 9 which are provided with suitable handles bywhich they may be readily turned on their pivots.

10 designates what I term a pusher. It is Specification of LettersPatent. Application filed November 29, 1911. Serial 1V0. 662,966.

partment which is designed Patented Nov. 19, 1912'.

designed to extend into the chambered portion of the table, tachablysecured to a slide 12 which is movable on and transversely of frame 2.The

slide is supported byframe 2 and is movable on the plane of the table,its pusher 10 7 being always in horizontal alinement with the chamberedportion of the latter. The

means for moving the slide may be widely varied, and that shown will bereadily understood without a detailed description beyond stating that adriven shaft 13 carries eccentrics which impart reciprocatory -mo tionsto links 14 which are connected to the slide, the driven shaft derivingits power through suitable gearing from a main driving shaft 15.

On the table Ifplace two separate series of dies onmandrels 16 and 17.All of the mandrels 'are of similar formation in cross section, butthose of one series are reversed with respect to those of the otherseries.

and at its rear it is de- The mandrels of the two series alternate andall are extended longitudinally ofthe bed, their lengths slightlyexceeding that of the bed. The mandrels of each seriesare connected onlyat their outer ends ,lthe'connections permitting them to erally. In Fig.7 'I have shown-each alternate mandrel as having a head block 20 withopenings to accommodate a connecting cross rod 21, and Ihave also eralmandrels of the series 17 connected by a link 22 having oblong slots toaccommodate the shanks of the mandrels. The same construction isobserved at the other ends of the mandrels of the series 16. Each man-'drel is shown as having, in cross section, a nearly sphericalbody-portion 23 from which extends a longitudinally disposed flange 24,which flange, in the case of the mandrels of the series 16, isdownwardly extended while in the series 17 it is 'up? wardly extended.The series 16 normally remain on the table, butafter the metal has beenshaped by forcing the two series together, as in Fig. 5, the series 17is moved lengthwise from the,table and on to a support 25 adjacent tooneend of the latter, which support I have shown in Fig. 1 as beingcomposed of a series of suitabiy mounted rollers. To prevent thecompleted sheet from passing off the table with'the series of mandrels17, I employ a stripper 26 located .at one end of thetable and designedto probe moved latshown the-sevject into the path of the sheet toprevent it from traveling with the mandrels as they are withdrawn. Thisstripper I have shown as pivotally mounted on the underside of the tableand as having a suitable manipulating handle. After the series ofmandrels 17 has been withdrawn the corrugated sheet may be removed fromthe bed.

Initially, the sheet which is to be shaped is, by any suitable means,given the formation shown in cross-section in Fig; 4. There is nodifficulty in so corrugating a sheet, but heretofore it has beenpractically impossible to form a sheet with corrugations having throatsof less width than the oppositely extended spherical bodies. With theseries of mandrels 16 sufficiently spaced apart on the table, thecorrugated sheet is placed over them as shown in Fig. 4. Thereupon theseries of mandrels .17 is slid longitudinally of the table and over thesheet, and caused to alternate with the mandrels 16. The severalmandrels of the'two series will then be spaced apart as shown in Fig. 4.Thereupon the operator lowers the top or cover 6 and fastens it by lugs9, and the operating shaft'being set in motion the eccentrics will forceslide 12 forward,

causing the pusher 10 thereof to engage with the innermost mandrel aswell as the inner edge of the corrugated sheet and force the: severalmandrels together until they assume the compact arrangement shown inFig. 5. The further revolution of the eccentries will withdraw thepusher, whereupon the operating mechanism is brought to a stop; the topor cover is then raised, and the corrugated sheet removed after theseries of mandrels 17 has been drawn outwardly 'onto the support I 25.The corrugations formed in the sheet will freely yield in be- .ing drawnover the enlarged body portions 23 of the lower series 0 mandrels, Theextent of the cooperation between the pusher'and the vertically disposedwall of the supporting table may be regulated by adjusting screws 4.

From what has been said it will be seen that by means of my invention Iam enabled" to form corrugations of the character stated extendinglongitudinally of the sheet, thereby giving to the latter additionalstrength in the direction most desired. Sheets thus corrugated areespecially designed for reinforcing concrete.

I claim as my invention 1. In a machine'for shaping metal from acorrugated sheet, two series. of dies or:

mandrels between which the sheet is compressed, the mandrels of eachseries being reversed in respect to the mandrels of the other series, atable supporting said mandrels, one series of mandrels projecting beyondthe table at one end thereof, and the other series projecting beyond theother endaoaaoea uponwhich one series of mandrels may be I moved.

2. In a machine for shaping metal from a corrugated sheet, a tablehaving a compressing chamber open at one side, two series of similarlyformed but reversely arranged alternating mandrels located within saidchamber, one series of mandrels projecting beyond the table at one endthereof, and the other series projecting beyond the other end of thetable, the projecting ends of the mandrels having shanks and headblocks, the latter being formed with coincident openings, links havingslots to accommodate said shanks, rods, projecting through the openingsof the head blocks, a horizontally-movable pusher designed to enter theopen side of said chamber to engage the adjacent mandrel and force theseveral mandrels together, and means for operating the pusher.

3. In a machine for shaping metal from a-corrugated sheet, a table"having ,a cornpressing chamber open at one side, two series ofsimilarly formed but reversely ar-' ranged alternating mandrels locatedwithin said chamber, a horizontally-movable pusher designed to enter theopen side of said chamber to engage the adjacent mandrel and force theseveral 'mandrels together, means for adjusting the position of thetable relatively to the pusher, means for operating the pusher, asupport adjacent to one end of the table ,onto which the mandrels of"one series are designed to be moved, and a stripper mounted on thetable adjacent to said support for preventing the corrugated sheet frombeing withdrawn from the table with the mandrels.

4. In a machine for shaping metal'irom a corrugated sheet, a, frame, atable having a compressing chamber open at one side, a top or cover forextending over said chant ber, means for locking the top or cover to thetable, two series of similarly formed but reversely positioned mandrelsalternately arranged and extending longitudlnally of the table, asliding member mounted on said frame, a pusher carried by said slidingmember and located 'in line with and movable into said compressingchamber through the open side thereof', andmeans for reciprocating saidsliding member.

5. In a machine for shaping-metal from a corrugated sheet, a frame, atable having a compressing chamber open at one side, a top or cover forextending over said chamber, means for locking the top or cover to ed onsaid frame, a pusher carried 'by said sliding member and located in linewith and movable into said compressing chamber through the open sidethereof, means for reciprocating said sliding member, a support in linewith one end of the table upon which the mandrels of one .seriesaredesigned to be moved after the sheet has been formed, and a stripper forpreventing the formed sheet from following said mandreis when beingWithdrawn from the table.

In testimony whereof, I have signed this specification in the presenceof two subscribing witnesses.
